HOOK.

i SPECIFICATION forming part of Letters Patent No. 695,560, dated March 18, 1902.'. Application filed October 16, 1901. Serial No. 78,860. (No model.)

To @ZZ wtonc t maycocoe'n: n

Be it known that I, CHARLES B. JOHNSON, a. citizen of the United States, residing atCo-v lumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Hooks; and I do hereby or disconnect the strap and when connected' shall be secure against accidental disconnection.

In the accompanying drawings, illustrating an embodiment of the invention, Figure l is a view in perspective of a bridle-bit with pieces of the reins, cheek-pieces, andv billets of the overcheck depicting one important use of the improved hook. Fig. 2 is a side view of the hook alone on a larger scale. Fig. 3 is 'an edge View on a still larger scale, showing the movable or closing part of the hooksprung on its fulcrum or pivot and riding a stop on the stationary part of the hook. Fig. 4. i's a sectional view on the lines .fr on, Fig. 2, looking down, showing the part-s in closed and locked position.

In the several views, 5 designates the shank of the stationary part of the hook. This has an eye 5a, into whichthe end of, forinstance,VV

a billet 8 of an overcheck can be looped and buckled, as seen in Fig. l. The shank of the hookV is prolonged in about a half-circle arc, as indicated at 5b, to form the hook portion proper of the stationary part of the device.

The movable or closing part of the device comprises a tongue 6, with an arc-shaped prolongation 6b therefrom of the same curvature as that of the' part 5b. This movable or closing part is hinged on a pin 7 to the end of the stationary part, so that when the movable part is turned down into closing position the portion 6b will coincide with the portion 5b.

In this position the portion 6 of the movable part'of the devicecloses the opening between the end of the stationary part 5b and the shank of that part, as seen in broken lines, Fig. 2.

To lock from accidental opening the movable part to the stationary part, the stationary part is shown to be made with a protuberance 5c and the end of the movable part with a recess6; but the relative location of the protuberance and the recess can be reversed-that is, the protuberance can be on the movable part and the recess on the stationary part. The closing part ot' the device, as shown in full lines, Fig. 2, is in the open position, and from this position is moved to.

closed position by forcing the portion 6b down. In this operation the part 6b being forced against the protuberance springs laterally outward and rides over the protuberance 5c (see Fig. 3) until the recess 6a coincides with that protuberance, when the elasticity of the portion 6b closes them together, as seen in Fig. 4. In the closed position of the parts considerable pressure against the closing portion 6 is required to force the recess Ga away from the protuberance. Hence the parts are locked in closed position against any accidental opening of the hook.

When', for illustration, an overcheck bearing the hook is to be connected to the bit, as

seen in Fig. 1, the parts of the hook will be in' the open position indicated in full lines, Fig. 2, and the hook is closed on the bit by simply pulling upward on the billet-strap 8 of the overcheck, this operation drawing the portiolnl 6h down to coincide with the portion 5 The hooks when used for the purpose deeach other, and a protuberance 5c and a recess 6a on the opposing faces of the yparts 5b and 6b whereby the iieXible portion 6" must be flexed laterally and ride over the protnberztnee 5 to effect the locking' and unlocking of the parte, substantially as described.

2. A hook comprising a stationary part and a movable laterally-flexible closing-arm pivoted thereto and sliding thereon, a protnberance on the face of one part, and a recess in the face of the other to be engaged by the aforesaid protubernnce to lock the parts in 1o closed position, the closing part to be exed laterally to effect the engagement and disen- CHARLES B. JOHNSON'.
